\title{Connect observations by stairs.}
\usage{
geom_step(mapping = NULL, data = NULL, stat = "identity",
position = "identity", direction = "hv", ...)
}
\arguments{
\item{direction}{direction of stairs: 'vh' for vertical then horizontal, or
'hv' for horizontal then vertical}
\item{mapping}{The aesthetic mapping, usually constructed with
\code{\link{aes}} or \code{\link{aes_string}}. Only needs to be set
at the layer level if you are overriding the plot defaults.}
\item{data}{A layer specific dataset - only needed if you want to override
the plot defaults.}
\item{stat}{The statistical transformation to use on the data for this
layer.}
\item{position}{The position adjustment to use for overlapping points
on this layer}
\item{...}{other arguments passed on to \code{\link{layer}}. This can
include aesthetics whose values you want to set, not map. See
\code{\link{layer}} for more details.}
}

Connect observations by stairs.

\examples{
# Simple quantiles/ECDF from examples(plot)
x <- sort(rnorm(47))
qplot(seq_along(x), x, geom="step")
# Steps go horizontally, then vertically (default)
qplot(seq_along(x), x, geom="step", direction = "hv")
plot(x, type = "s")
# Steps go vertically, then horizontally
qplot(seq_along(x), x, geom="step", direction = "vh")
plot(x, type = "S")
# Also works with other aesthetics
df <- data.frame(
x = sort(rnorm(50)),
trt = sample(c("a", "b"), 50, rep = TRUE)
)
qplot(seq_along(x), x, data = df, geom="step", colour = trt)
